FRANK B. SOUTHWIOK, OF GRAND RAPIDS, MICHIGAN.

DUMP WAGON-WBOX.

SPECIFICATION forming part of Letters Patent No. 478,379, dated July 5, 1892. Application filed May 26. 1891; Serial No. 394,186- (No model.)

T0 00% whom it may concern.-

Be it known that I, FRANK B. SOUTHWIOK, a

citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Wagon Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that class of wagon-boxes adapted to dump or discharge their contents through the bottom; and its object is to provide such boxes with certain new and useful features hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings,in Wlll0h Figure 1 is a perspective of a device embodying my invention; Fig. 2, a plan viowof the same; Fig. 3, a vertical section on the line 00 w of Fig. 2, and Fig. 4 a detail of one of the hinges for the bottom boards.

A A are the side-boards, which are connected at each end bytrans-verse end-boards E E and also by cross boards orpartitions A E and E", arranged in pairs a short distance apart, one pair being located near the front and the other pair near the rear end of said box, the middle portion thereof being the receptacle for the load. The bottom of this middle portion consists of four hinged sections F, the two outer ones being hinged to the lower edge of the side-boards and opening downward and outward and the two inner ones hinged to a middle strip 0 and opening downward and inward toward each other; Said middle strip is of considerable vertical thickness, and its upper angles removed presenting oppositely-inclined surfaces. The hinges for the outer section consistof astraight strap G, extending vertically across and attached to the side-boardA, hinged at its lower end to one end of a laterally-curved strap G, which is quadrantal in form and secured to the under side of the section F, near the end thereof, Withits opposite end projecting from beneath the end of said section F and having attached the shackle P, to which is connected the cable or chain K, hereinafter described. The inner sections F have similar hinges, except that a single short strap G is secured to the bottom of 0, having each end hinged to the respective adjacent ends of the curved straps Each half of the bottom thus consists of two longitudinal hinged sections and held closed by the cables or chains K K, each pair being connected to asingle cable or chain K, which passes upward between the partitions E E and E E, thence over the vertical pulleys K K, thence horizontally throughthe sides of the box and over the horizontal flanged pulleys M, and thence toward the middle of the respective side-board, where they are connected to opposite sides of the lever H, the one from the front being connected to the lower end thereof and at the front side and the one from the rear connected at a suitable distance from the said end at the rear side of the lever. Said lever has a longitudinal slot- J midway between the points where the cables are fastened, through which passes a pivot bolt or stud I. Said slot J permits equalization of the strain upon the cables K K.

N is a notched sector to secure the free end of the lever when depressed.

O is the seat, having a strip attached at the-bottom, which enters the space between the partitions E E and secures the seat in place. The middle strip 0 extends throughout the entire length of the box, and the compartments at the ends of said box have fixed bottom boards, the forward compartment being open to accommodate the feet of any one sitting on the seat 0 and the rear compartment closed with a hinged cover D, forming a suitable feed-box or other receptacle.

L L are guide-strips to retain the cables or chains K in place when slackened.

B B are bolsters to raise the box sufficiently to enable the sections F to clear the hounds of the wagon. It will be observed that each lever operates the respective pair of bottom sections F F. \Vhen the said lever is depressed, as shown, and secured by the sector N, the said sections F are drawn up by the cables and firmly closed, and when said lever is released and raised to a vertical position the cables are slackened and said bottom sections swing downward and outward, thus discharging the contents of the box. The said sections overlapping the side-boards and middle strip on the under side prevents any leakage,

and the same, together with the inclined upper surfaces of the middle strip 0, prevents lodgment of any of the contents of said box.

What I claim is- 1. In a wagon-box, the combination of two pairs of hinged sections, a strip between the inner section of each pair, straps G" and G, pivotally connecting said inner sections to said strip, said straps G being curved, straight straps G, secured to the sidestof the box, laterally-curved straps G, each pivotall y secured at one end to the lower end of a strap G and secured to one of the outer sections near an end thereof and projecting from beneath said end, levers secured to the sides of the box, a cable connecting each of said le vers with the adjacent ends of the pairs of curved straps G, and pulleys over which said cables pass. 1

2. A wagon-box having transverse partitions located in pairs near each end and forming two chambers located one at each end of the part for the load, a longitudinal strip located between said chambers atthe center of the load portion of the box, two pairs of hinged sections located on opposite sides of said longitudinal strip and forming, together with said strip, the bottom of the load portion of the wagon-box, the inner section of each pair being hinged to said strip and the outer section of each pair being hinged to the sides of the box, vertical pulleys located within said chambers, horizontal pulleys also located within said chambers and journaled in the side-boards of the box, levers pivoted to said side-boards,and cables or chains attached to said-levers, extending over said pulleys and attached to said bottom section, all combined and operating substantially as set forth.

3. In a wagon-box, the bottom thereof, consisting of two pairs of hinged sections and a longitudinal strip located between the pairs of sections,in combination with straight straps G G", secured, respectively, to the sides of the box and the under side of said strip, and laterally-curved straps pivotally secured to opposite sides and the lower ends of said straight straps, as shown, each of said curved straps being also secured to one of the sections of the bottom near an end thereof and projecting from beneath said end, chambers at opposite ends of said sections, horizontal and vertical pulleys in said chambers, a lever secured to each side of the box, and a cable connecting each of said levers with the ad acent outer ends of the curved straps and engaging said pulleys, substantially as described, whereby none of the operating mechanism will be located in the load portion of the box, as specified.

4. The combination of a wagon-box having a bottom consisting of hinged sections, cables or chains extending from opposite ends of said sections to a lever and attached to the same atopposite sides and at a distance from each other, said lever having a slotted opening midway between said points of attach ment, and a pivot stud or bolt passing through said slotted opening, substantially as described.

5. In a wagon-box, a bottom consisting of longitudinal sections having hinges, consisting of straight straps attached to the box and curved straps attached to said sections and projecting from the end thereof, and cables or chains extending over pulleys and connected to levers for operating said sections, substantially as described.

6. In a wagon-box, the combination, with hinged sections forming the bottom thereof, straight straps secured to the sides of the box, and curved straps, each pivotally securedat its outer end to the lower end of one of said straight straps, said curved straps being also secured to said sectionsnear the end thereof and extending beyond said ends, of chambers at opposite ends of said sections, pulleys in saidchambers, cables secured to the ends of the curved straps and extending thence over said pulleys, and means for operating said cables to raise and lower said sections.

7. In combination, a wagon-box havingparallel transverse partitions, as E E, and a seat having attached a strip, as 0, adapted to be inserted between said partitions, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
